摘要
Since a long time, the European eel, (Anguilla anguilla, L.), is appeared as a common species and a major fish component in littoral (lagoons, estuaries and coastal marshes) and continental waters (catchments areas, ponds). The significative diminution of its continental abundance has been revealed by many scientific studies. This consciousness is appearing too either among the technical teams working within the different catchments either among the privileged witnesses that are fishermen. It comes to management actions performed at various spatial scales. This report places the context of the Eel Report Card of the Loire catchment, defined in 2000 under the shield of the COMMITTEE of MANAGEMENT MIGRATORY FISH of the Basin of Loire, Vendeans Coasters and Sevre Niortaise. It has been taking place in April 2002. Its objective in fine is to contribute to a management and a sustainable development of the species and habitats. This Eel Report Card organizes a regular and objective acquisition of data characterizing the evolution of the stock in place and of the available habitats. This project brings indicators permitting to fix alarm levels and to value impacts of various measures of management. To lead to well the Eel report Card, it is necessary to end at two indicators of state (quantitative and qualitative): (1) of the eels population to each phase of his biological cycle; (2) of the habitat accessibility for the species within the Loire catchment area. The concept, the working and applications of this Eel Report card are presented in this paper.
